The structural relationships of the longitudinal fibromuscular component of the soft palate (musculus uvulae and raphe) were studied using histologic sections from 19 early human fetal specimens. Musculus uvulae arises in association with the palatine aponeurosis near the beginning of the second quadrant of the velum, follows a sigmoid course, and terminates near the base of the uvula. In addition, an occasional muscular loop may arise from the bony palate, arch downwards, and then recur into the uvular muscle. A complex relationship exists between the raphe in the velum and several palatal muscles. With regard to musculus uvulae, small muscular bundles arise from the raphe to embrace the muscle near its crest. These branches may aid in contouring the dorsal surface of the velum in the region of the levator eminence to complement the surface of the posterior pharyngeal wall and thus enhance the efficiency of the velopharyngeal seal.
利用19例早期人类胎儿标本的组织学切片，研究了软腭纵向纤维肌肉成分（悬雍垂肌和正中缝）的结构关系。悬雍垂肌在腭帆第二象限起始处附近与腭腱膜相连，走行呈S形，止于悬雍垂基部附近。此外，偶尔会有肌袢从硬腭发出，向下弓形弯曲，然后折返进入悬雍垂肌。腭帆正中缝与几块腭肌之间存在复杂的关系。就悬雍垂肌而言，有小肌束从正中缝发出，在肌嵴附近包绕该肌。这些分支可能有助于在提肌隆起区域塑造腭帆的背面，以补充咽后壁的表面，从而提高腭咽闭合的效率。
